Galactic Panspermia
Idan Ginsburg, Manasvi Lingam, Abraham Loeb
We present an analytic model to estimate the total number of rocky or icy objects that could be captured by planetary systems within the Milky Way galaxy and result in panspermia s…
Tidal Disruption Events and Gravitational Waves from Intermediate-mass Black Holes in Evolving Globular Clusters Across Space and Time
Giacomo Fragione, Nathan Leigh, Idan Ginsburg +1
We present a semi-analytic model for self-consistently evolving a population of globular clusters (GCs) in a given host galaxy across cosmic time. We compute the fraction of GCs st…
A dynamical origin for planets in triple star systems
Giacomo Fragione, Abraham Loeb, Idan Ginsburg
Recent radial velocity and transit data discovered planets in binary or triple stellar systems out of the entire population of a few thousand known planets. Stellar comp…
Dating the tidal disruption of globular clusters with Gaia data on their stellar streams
Sownak Bose, Idan Ginsburg, Abraham Loeb
The Gaia mission promises to deliver precision astrometry at an unprecedented level, heralding a new era for discerning the kinematic and spatial coordinates of stars in our Galaxy…
Revisiting hypervelocity stars after Gaia DR2
Douglas Boubert, James Guillochon, Keith Hawkins +3
Hypervelocity stars are intriguing rare objects traveling at speeds large enough to be unbound from the Milky Way. Several mechanisms have been proposed for producing them, includi…
